A Venture Synthesis and Fabrication of BiVO 4 as a Highly Stable Anode Material for Na‐Ion Batteries

Abstract Needle‐like BiVO 4 anode material for Na‐ion batteries was prepared by a simple solvothermal technique at 100 °C without further calcination. The BiVO 4 electrode exhibited initial discharge (sodiation) capacity of 897 mAh /g with coulombic efficiency of 70.68% at 100 mA /g. The average coulombic efficiency was estimated at 93.07% and sodiation capacity predicted at 432 mAh/g upto 200 cycles. The average sodiation/desodiation capacity retention were found to be 52.07 and 68.10%, respectively for more than 100 cycles. The results demonstrate that needle‐like BiVO 4 anode material offers an excellent electrochemical performance for large‐scale energy storage applications.
